If you use spermicidal foam, gels or cream, or lubricated condoms with added spermicide, they often contain the chemical nonoxynol-9 (or N-9). Since it's something you put inside your body, it's important to know about it. Take this quiz to test your knowledge.

1/2 haha! I didn't know it was 71%! I thought that was kind of high for just using that!
1what exactly does nonoxynol-9 do to the sperm? how does it kill them?
2How about the other gritty? Nonoxynol-9 can trigger yeast infections. Use with caution ladies!
3Nonoxynol-9 is not nice to me.
4It just seems like more mess and money than it's worth, given that it's not even more effective than a condom - which is cheaper, faster, and easier.
5Good call Plucky18--I got my very first yeast infection from condoms lubricated witht his stuff. Be cautious...
6Wow 100%! Haha and I've never heard of this brand!
7I didn't know people still used this stuff. I thought all the benefits of killing HIV was just under ideal conditions (test tubes), not practical use? It just seems like something you would hear about watching a 1980s movie, lol.
8Does this stuff burn anyone else?
